The Col de Pavezin is certainly not the highest, but it is no less mythical. The inventor of the derailleur, Paul de Vivié, who settled here, made it an unmissable rendezvous. The pass is located between the Rhône valley and the Gier valley, and opens up a grandiose panorama of the Alps and the Rhône furrow.

THE crossroads of all the walks in the area, with the little refreshing break at the inn, it's perfect (change of owner in progress, for the moment it is closed)

The Col du Pilat. A billiard-style surface from Le Collet. It's worth continuing the climb to Crêt de la Botte (second antenna after the parking lot) for a nearly 360-degree panorama.
